gravitational force and circular motion

Question 1

what is a field of force

Answer 1

a region of space where a particle experiences a force

Question 2

gravitational potential

Answer 2

work done in bringing a unit mass from infinity

Question 3

gravitational force

Answer 3

is a force that attracts any two objects with mass

Question 4

newtons law of gravitation

Answer 4

force between two point masses is directly proportional to the product of the masses and indirectly proportional to the square of separation

Question 5

gravitational field strength

Answer 5

force per unit mass

Question 6

difference between polar and geostationary orbits

Answer 6

Geostationary satellites remain in the same place relative to Earth and low polar satellites move, covering every part of the Earth’s surface in only a short time frame
